Monitoring BLSH open interest helps you see where real money is positioned on Bullish's options and which strikes are attracting the most commitment from traders. Bullish's open interest reflects the total number of outstanding contracts that have not been closed or exercised, making it a powerful gauge of liquidity, conviction, and potential support and resistance zones. Use our scanner to monitor BLSH options open interest in real time and find the strikes that matter.
Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising BLSH options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Bullish to settle.
